Bosch 13358 Oxygen Sensor - Downstream Right

Bosch Oxygen Sensor for Kia and Hyundai

Bosch Validated Oxygen Sensor 13358 is a specific-fit, narrow-band heated O2 sensor built for downstream right applications on select Kia Sportage and Hyundai Tucson models. It provides the ECU with accurate air-fuel-ratio feedback to support stable combustion control and lower emissions.

Backed by Bosch’s long OE development history, this sensor uses a threaded metal housing, a 4-wire blade-terminal design, and an included wiring harness for a direct replacement-style installation. Bosch 13358 is engineered for consistent signal response under heat and vibration, making it a practical choice for emission control service on the Kia Sportage and Hyundai Tucson.

Key Features

• Specific-fit Bosch Validated Oxygen Sensor for downstream right placement
• Narrow-band heated oxygen sensor design for closed-loop fuel control
• 4-wire configuration with square connector and male blade terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing with high-temperature-resistant construction
• Wiring harness included for service replacement
• Cross-reference: Monroe Shocks & Struts (e.g., 3921037523) for the same application

Product Details

Bosch part number 13358 is part of the Bosch Validated Oxygen Sensor line, which reflects Bosch’s OE-focused approach to oxygen sensing technology. This line builds on Bosch’s early thimble sensor development and later planar narrowband designs, emphasizing faster sensor response, improved lambda accuracy, and quicker closed-loop operation. For drivers servicing a 2005-2010 Kia Sportage or 2005-2009 Hyundai Tucson, this sensor is a direct-fit emission control component for the downstream right position.

Compatible With 2005-2010 Kia Sportage, downstream right, and 2005-2009 Hyundai Tucson, downstream right. Bosch 13358 is a standard replacement sensor with a 26.2 overall length and 24.8 wiring harness length, built to deliver steady feedback to the engine control unit across changing operating conditions.

Common Issues This Part May Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings at the ECU
• Reduced closed-loop fuel control response
• Higher-than-normal emissions output
• Sensor degradation from heat and vibration exposure

Installation Notes

Verify the downstream right sensor location before installation and confirm the 18 mm threaded mounting point matches the vehicle. Use the existing harness routing and connector orientation to avoid strain on the lead, and inspect the exhaust threads and sealing surface before fitting the new sensor. Because this is a heated narrow-band sensor, proper connector engagement and secure wiring placement are important for stable operation.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, and the Validated Oxygen Sensor line is built to meet the demands of everyday aftermarket service with OE-proven design principles. Bosch 13358 is engineered for durable signal accuracy and dependable performance in emission control applications.
